SOURCE: I have a 2005 LS430;

Try this: turn off the Smart Access (button under the kick panel) and then put the key in the switch and then try to turn it (while wiggling the steering wheel), it won't turn otherwise - it's a safety system. If that fails , and the fact that the doors aren't opened with the fob shows that the signal from the fob isn't recognized by the security system of the car.
This can be caused only by 2 things: either the security system or the key fobs are defective or have become in some way unpaired. A visit to a dealer is mandatory in this case, they will have to test the system and reprogram it.

Will not start

if the immobiliser unable to sync with key or card, the ECU will cut out the power to stop the engine. Check if you have the immobiliser indicator turn on.

Changed out ignition switch but security light wont turn off after trying to relearn key

This can be a very touchy system. One wrong move on install can damage things down the line. Ive had good luck bypassing these systems. No more smart keys, no more security lights.

Turns over upon starting, but will not ignite.

what you need to check is to see if the security light goes off when the key is inserted to make sure the key is still programmed to car when in ignition. Then the basics for a car starting: air, fuel, compression. couldbe alot of things but check the timing on the car, incase it jumped a tooth or timing belt broke. May need tune up: spark plugs. please post more information about problem with car. also check battery cables for corrision.

2001 lexus ls430. Dead battery at airport. jumoers turned over starter fine but car would not start and no dashboard lights, fan, radio but driver and front passenger windows and doorlocks worked but not...

Sounds as though when your battery died the engine imobiIiser locked down.
If you have your wallet key as well , try taking all to the airport. HOLD the card to the dash beside the ignition for at least 20 seconds, then try turning the key several times. I haven`t done an LS but the failsafe when a remote fails is to hold the key beside the ignition for at least 20 seconds ....
Also try the lock routine, but I think the issue is in needing to reboot to your key.
My understanding is that the lock routine re initialises the lock setstings when power is restored

Broken key car wont start

i had the same thing happen to me. you have a smart key and there is a chip inside the key that must be read by the security skin in your ignition your car will start three times and if the chip is not presented to the security skin transducer then it will lock your ignition out so the car will not start. Two options one if you have a spare key use that and try turning the ignition on and leave the car set for 3-4 hours this will generally clear the lock out. If that does not work then you will need to get a new key from the dealer and have them flash your car's PCM or get the new blank key and call an area lock smith and have them reprogram your key and reset your antitheft module on your car.
